BOAT-PROPELLING DEVICE.

Application led J'une 26, 1923. Serial No.`647,934-.

To all lzii/0m t may concern.'

Be it known that I, CLIFFORD A. JoYNnR, a citizen of the United States,residing at Muncie, in the county of Delaware, State ot' indiana, haveinvented a new and useful Boat-Propelling Device; and l do herebydeclare the following to be a full, clear, and exact description of theinvention, such'as will enable others skilled in the art to which italipertains to make and use the same.

The invention relates to boat propelling devices, and has for its objectto provide a device of this character which is manually operated andwhich rotates a propeller through a gear train, upon the oscillation ofa pivoted handle having a pitman connection with one o-f the gears intheY gear train.

A further object is to pro-vide one of the gears of the gear train witha weight acting as a fly wheel for adding momentum during the operationof the device and insuring a positive operation thereof.

A further object is to mount the device on a single bracket therebyallowing the device to be applied to various types of boats, forinstance a row boat, launch or canoe.

A furtherobject is to provide the rear end of the bracket with spacedbearings, in which bearings the propeller drive shaft is mounted, andbetween which spaced bearings the propeller drive shaft gear is disposedand driven through a gear train connection with an operating lever, anda. pitman.

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter' set forth, shown inthe drawing, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spiritoi the invention.

ln the drawing Figure 1 is a side elevation of a conventional form ofboat, showing the propelling means applied thereto.

Figure 2 is a top plan view of the propelling device.

Referring to the drawing, the numeral 1 designates a conventional formof boat, which is preferably a small one and 2 a seat disposed therein.Secured to the inner side ot the bottom 3 of the bolt by means of rivets4 is an elongated bracket 5, which bracket is preferably formed fromsuperimposed bars 6, the rear ends of vided with spaced upwardlyextending arms 7 in bearings 8 of which the propeller shaft 9 isrotatably mounted. Extending upwardly and rearwardly from the forwardend of the upper bar 6 is an integral arm 10, to the end of which ispivotally connected at 11 an operating lever 12. lVhen the device isoperated, the operator preferably seats himself on the seat 2, thengrasps the cross handle 13 of the operating lever 12, and oscillates thesame on its pivotal point 11. Connected to the lower end 111 of theoperating lever 12 by means of a universal connection 15 is a pitman 16.The pitman extends rearwardly and is pi'votally connected at 17 to themain drive gear 18. Drive gear 18 meshes with a small gear 19, which `iscarried by a large horizontally disposed gear 20, which gear 20 mesheswith the propeller shaft carried gear 21, consequently it will be seenthat when the main drive gear 18 is rapidly rotated by the oscillationof the operating lever 12, the propeller shaft 9 will be rapidly rotatedand consequently the propeller 22 will be rapidly rotated for propellingthe boat. To add momentum to the operation of the motor, a fly wheel 23is provided on the upper side of the gear 20, which fly wheel insures asteady opera-tion of the gear train and adds momentum to the movingparts of the motor during the operation thereof.

From the above it will be seen that a hand operated motor is providedfor small craft which is positive in its operation, carried by a singlebracket and may be easily and quickly attached to a. boat and operatedby a single person or a numberof persons. It will also be seen that byproviding a gear train that rapid rotation of the propeller 22 may beobtained upon a single oscillation of the handle member 12.

The invention .having been set forth what claimed as new and vuseful isA manually operated motor for small craft, said motoi` comprising anelongated bracket adapted to be secured to a boa-t. spaced arms carriedby the rear end of said bracket, a propeller drive shaft mounted inbearings of said spaced arms, a gear carried by the propeller driveshaft and disposed between the spaced arms, a gear train carried bv saidbracket and geared to the gear carried by the propeller drive shaftbetween which are proloo the spaced arms, the forward end of said nameto this specification in the presence of bracket bleing proyided withupwardly and two Subscribing Witnesses. rearwarc exten in0` arm an oeratinor ler Ver pivotily oonneced to saidparm aid a CLIFFORD A Jox NER'5 ptma-n connection between the operating le- Witnesses:
